Parking are 8$USD for an hour. =)
Flights are priced depending on where you are going, food is priced differently at each restaurant.
How much does it cost what? Travel, food, beverage. Hotels. What's your question?
It's free to go the Airport!
Roughly around 10 billion US dollars for a small airport with 2 runways that can comfortably serve a fair travel service facility for domestic flights. There already is an international Airport, so there is no need for that.
If you have to ask, then maybe you should not go.
Prices will vary. Go to your designated airline websites and browse the prices.
